## Retrieve transaction value ### Instructions Targeting a local bitcoin node, create a function `retrieveTransactionValue()` that takes as input a hash of a simple transaction, and returns the total value transferred in this transaction in bitcoins. If several outputs are sent, the value should be summed up. The Bitcoin node RPC interface is expected to be running with the following parameters: ```bash rpcallowip=127.0.0.1 rpcport=18443 rpcuser=leeloo rpcpassword=multipass ``` ### Usage ```js const { retrieveTxValue } = require('./retrieveTransactionValue.js') retrieveTxValue( 'd030023d96b9170af9ec2fe5d9b62a5eacbcbf144c68f3f45d68bca72d1d3649', ) // Expected : 50 ``` ### Hint Internally, Bitcoin uses satoshis, 1 satoshi = 10^-8 bitcoin ### Notions - [Node.js https module](https://nodejs.org/api/https.html) - [Async function in Javascript](https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Statements/async_function) - [satoshi]()
